Abstract: Methods and apparatuses for performing multi-window control in a user interface are disclosed. In some embodiments, the method includes displaying the user interface in a display of an extend reality (XR) device, where the user interface includes a graphical user interface (GUI) element and a number of objects. The method can also include detecting selection of the GUI element in the UI; moving a set of objects being displayed on the display into a window on the display; detecting a selection of one or more of objects in the set of objects by tracking movement of a user; and displaying selected objects of the one or more objects in front of a user.

Abstract: Systems and methods are disclosed for calibrating an image sensor using a source image taken from the image sensor and comparing it to a reference image. In one embodiment, the method may involve determining the luminance and chrominance values of portions of the image at successive frequency levels and calculating a standard deviation at each frequency level for both the source image and the reference image. The standard deviation values may be compared and a difference determined. Using unit vector search vectors, noise values may be calculated to determine sensor calibration values.
